MACHINE FOR DRAWING WIRE.

SPECIFICATION forming part of Letters Patent N0. 770,044, dated September 13, 1904.

Application filed July 21, 1902. Serial No. 116,336. (No model.)

To aZZ whom it may concern.-

Be it known that I, ELBERT I-I. CARROLL, a citizen of the United States, residing at Worcester, in the county of Worcester and 5 Commonwealth of Massachusetts,have invented a new and useful Improvement in a Machine for Drawing Wire, of which the following is a specification, accompanied by drawings forming a part of the same, in which I Figure 1. represents a side elevation of a machine for drawing wire embodying my invention. Fig. 2 is a central vertical sectional view of the rotating block or drum upon which the wire is wound, said section being taken I on the line 2 2, Fig. 5. Fig. 3 is a vertical sectional view of the rotating block or drum on the radial line 3, Fig. 5. Fig. 4: is a top View of the supporting-framework, showing the rotating spindle with the drawing block 29 or drum removed therefrom. Fig. 5 is a plan view of the rotating block or drum with onehalf shown in sectional view. Fig. 6 is atop view of the clutch member carried by the rotating spindle, and Fig. 7 is a top view of the 2 5 oil-receptacle.

Similar reference-figures refer to similar parts in the different views.

The object of my present invention is to provide a machine for drawing wire in which 3 the rotating block or drum upon which the drawn wire is wound is so connected with the driving power as to overcome the sudden shock incident to starting the drawing-block, to provide eflicient and durable means for frictionally connecting the block with the driving power, and, further, to enable the connection between the block and the driving power to be completely under the control of the operator while starting the wire through 4 the reducing-die, and I accomplish this object by the construction and arrangement of parts as hereinafter described, and set forth in the annexed claims.

Referring to the accompanying drawings, 1 denotes the supporting-framework, in which is journaled a horizontal driving-shaft 2, by

which a vertical spindle 3 is rotated by means of the connecting beveled gears 4 and 5. The vertical spindle 3 carries a clutch-collar 6, consisting of a circular disk provided with a 5 transverse driving-rib 7, which engages a corresponding recess 8 in the under side of a cupshaped oil-receptacle 9, which is provided with a concentric hub 10, inclosing the upper end of the vertical spindle 3. Between the central hub 10 and the outer wall 11 of the oil-receptacle 9 is an annular chamber 12, which contains a driving-ring 13, provided on its lower surface with projections 14:, which engage corresponding recesses 15, Fig.7, in the bottom of the oil-receptacle, so that the rotation of the latter will be imparted to the driving-ring 13. Supported upon the top of the central spindle 3 is the inverted cup-shaped block or reel 16, provided with a concentric 5 Y depending flange 17, extending downward into the annular space 12 of the oil-receptacle. Surrounding the outer wall 11 of the oil-receptacle 9 is a ring 18, provided with an interior downwardly-depending friction lip or 7 flange 19, having a beveled surface adapted to be brought into frictional contact with the interior beveled surface 20 upon the inside of the oil-receptacle 9.

The lower edge of the ring 18 rests upon rolls 21, carried in a yoke 22, which is journaled in bearings 23 on the framework of the machine and is provided with an outwardlyextend ed arm 24, which is connected by a link 25 with a treadle 26, pivoted at 27 to the framework of the machine and provided at its forward end with a step or stirrup 28, by which the treadle may be depressed by the foot of the operator. The ring 18 carries a stud 29, extending through a slot 30 in the 5 flange 17 and having its inner end in contact with the upturned end 31 of a spiral spring 32, which is loosely wound in a coil around the periphery of the driving-ring 13, the opposite end 33 of the spring 32 entering a slot 9 34 in the flange 17. The yoke 22 is connected by a spring 35 with a fixed arm or bracket 36,

by which the friction-rolls 21 are depressed and the treadle 26 normally held in a raised position.

When the rolls are depressed, the ring 18 is allowed to fall until its friction-lip 19 rests upon the friction-surface 20 on the inside of the oil-receptacle 9. The frictional contact between the lip 19 and the side of the oil-receptacle causes the ring 18 to be rotated by the oil-receptacle, carrying the stud 29 against the end 31 of the coiled spring 32, which tightens the coiled spring 32 on the periphery of the driving-ring 13 and causes the rotation of the driving-ring to be imparted to the coiled spring and through the end 33 of the coiled spring and flange 17 to the block or reel 16. By depressing the treadle 26 the rolls 21 will be raised, thereby lifting the lip 19 of the ring 18 out of frictional contact with the side of the oil-receptacle 9 and allowing the elastic coiled spring 32 to become loosened by the periphery of the driving-ring 13, which will continue to revolve within the coiled spring 32, permitting the drawing block or reel 16 to come to a state of rest. As the rolls 21 are lowered the friction-ring 18 is carried down by gravity, also aided by the pressure of a series of spiral springs interposed between the friction-ring 18 and the top of the wire-drawing block 16, one of said springs being shown at 37 Fig. 3.

The top of the wire-drawing block or reel is slotted at 38 to receive a projecting handle 39, held in the friction-ring 18 in order to enable the operator to move the ring 18 independently of its frictional connection with the oil-receptacle 9 for the purpose of tightening the coiled spring 32 on the periphery of the driving-ring 13. The drawing-block is provided with the usual gripping mechanism for seizing the end of the wire to be drawn and comprising the jaws 10 41,with means for closing the jaws upon the wire. The oil-receptacle 9 is filled with oil, which prevents the abrasion of the driving-ring 13 and coiled spring 32 when they slip upon each other.

The operation of my improved wire-drawing mechanism is as follows: The end of the wire to be drawn is pointed and entered through the usual wire-reducing die, and the end is then seized with a pair of tongs, which are connected by a chain with the wire-drawing block 16. The operator then moves the ring 18, by means of the projecting handle 39, to carry the stud 29 against the end 31 of the coiled spring 32 in the direction to wind the spring upon the rotating driving ring 13. The bight of the spring 32 on the ring 13 rotates the spring, and its end 33 entering the slot 34: in the flange 17 causes the drum 16 to rotate and draws the wire through the reducing-die until the end of the wire can be released from the tongs and seized by the jaws -10 11, when the rolls 21 are depressed by the release of the treadle 26, which is normally held locked in its depressed condition. The depression of the rolls 21 allows the ring 18 to fall and bring its friction-lip 19 into contact with the friction-surface 20 of the rotating oil-receptacle, thereby winding up the coiled spring 32 on the periphery of the driving-ring 13 and rotating the drum 16, winding the wire thereon as it is delivered from the wire-reducing die. The depression of the treadle 26 by the stirrup 28 will raise the ring 18 and immediately disconnect the drum 16 from the driving power.
